"......Seacast tm uses chopped reinforcement recycled fiberglass where others use ceramic spheres. In comparison fiberglass strands provide superior tensile strength better than ceramic spheres. Pound for pound, we dropped a 20 lb. weight from 10 feet creating 200 ft lbs of force. The difference is we dropped it once on the competition and they split and broke on the first drop. We dropped it 20 times on the Seacast tm, which resulted in just minor cosmetic damage."

EDIT:
Btw while 200 ft/lbs sounds impressive... I figured the force of impact for their test at 60759 lbs of pressure at assuming very little (.001 meters) compression upon impact...
